Global Warming Adaptation
Mangroves: It is the first line of defence for rising sea level. These plants can grow very well and very fast in sea water. These are pneumatophores. The roots of these rise above high tide sea level and breath normally. These plants are hardy and can grow upto 10 meters (40 feet) tall and have up to 125 mm (5 inches) stem at the root. It roots penetrate deep and can hold fast. As these grow, the size of root increases and the roots push other trees into sea. These can planted by planting stems or branches of older trees into marshy land. In this manner, the land sinking into sea can be gainfully utilized. The image below shows arial view of mangroves in 10 hectares of marshy land on coast line of our area, and top image shows the trees of the same area, as seen from ground level.
The branches of these trees can provide fire wood to local population as cooking fuel. Mangroves generate between US$ 2000 to US$ 9000 per hectare annually from fishing.
